People are visual creatures, and we equate poor design with poor products. Putting a little more time and money into making your work streamlined can, quite literally, pay off. Visitors will view you as more professional and will essentially trust you and your recommendations much more, making it far easier to become successful as an affiliate marketer.
BitDegree affiliate program is one of the best affiliate programs to earn easy money. There’s no application forms or fees.

Look for a gravity score of 30 or more, because these products have a proven track record of selling well for a number of different affiliates. Products, especially new products, with gravity scores under 30 may work but are more risky. Gravity scores of greater than 100 mean the product’s popular. You could have competition, but don’t worry about that. The important thing is that there’s lots of demand.

While any “regular” job requires you to be at work to make money, affiliate marketing offers you the ability to make money while you sleep. By investing an initial amount of time into a campaign, you will see continuous returns on that time as consumers purchase the product over the following days and weeks. You receive money for your work long after you’ve finished it. Even when you’re not in front of your computer, your marketing skills will be earning you a steady flow of income.

Creating blog content is a very useful and effective way of consistently building content on a site. When creating blog posts, it's a good idea to do some keyword research to figure out what it is that your audience is interested in and searching for online. Also, be sure to research competitors, forums and social media to narrow down on topics for your blog.

In February 2000, Amazon announced that it had been granted a patent[13] on components of an affiliate program. The patent application was submitted in June 1997, which predates most affiliate programs, but not PC Flowers & Gifts.com (October 1994), AutoWeb.com (October 1995), Kbkids.com/BrainPlay.com (January 1996), EPage (April 1996), and several others.[8]

It can be published as a book, and other people have already suggested what to include into ‘part 2’. As someone who has been asked by other people wanting to promote my products/serviced, I’d love to read about the merchant’s side of AM, e.g. various software that can be used, how to choose affiliate partners, what to include in the agreement, etc.
#2: Another great program is Jon Dykstra's Niche Tycoon. This focuses on paid traffic and outsourcing content to make money with Google Adsense (and similar programs). It requires a bit more of a budget, and also has less of a support community than Wealthy Affiliate, so it's best for people with a bit of online marketing experience and some money to get their business going.

Amazon's commission rate is pennies from each dollar of merchandise that you sell. What many people don't know is that there are affiliate opportunities out there that pay commission rates that are much more favorable, from $20-$100 (and even more). Browse affiliate networks like Commission Junction, Share-a-Sale, Rakuten and Ejunkie for opportunities and their general commission rate.
